GOLF-BALL.

SPECIFICATION forming part of Letters Patent No. 710,754, dated October '7, 1902. Application filed July 30,1902. Serial No- 117,608. (No model.)

To all whom, it may concern.-

Be it known that LRIOHARD B. CAVANAGH, a citizen of the United States, residing in \Vashington, in the District of Colu mbia,have

invented certain new and useful Improvements in Golf-Balls, of which the following is a specification.

This invention relates to golf-balls; and its object is to produce at low cost a durable ball IO which has good flying power.

The accompanying drawing illustrates, partly in section, a golf-ball made in accordance with my present invention.

Upon acenter piece A, principally orwholly of soft rubber or other soft resilient material, I apply a thick sphere B, consisting of paper or paper-pulp. The sphere B is highly com pressed and may, if desired, be formed in segments and then united under great pressure upon the center piece A. I then apply a gutta-percha shell C under heat and pressure in such a manner as to hold the filling B under high compression. At the operation of applying the shell C the gutta-percha is softened by the heat, and the paper filling I3 is caused to join firmly to said shell, practically all over the interior surface thereof, thereby making the ball of good flying quality and great durability.

Variations may be resorted to Within the scope of my improvements.

Having described my invention, I claim 1. A golf-ball comprising a springy center piece, a thick sphere thereon of compressed paper, and a shell of gutta-percha which adheres to the paper.

2. A golf-ball comprising a soft-rubbercenter piece, a thick solid sphere of paper thereon, and a shell of gutta-percha which adheres to the paper sphere.

3. A golf-ball comprising a sphere of paper, said sphere being formed of half-shells, a soft, springycenter piece, and a gutta-percha shell.

i. A golf-ball comprising a center piece formed at least partially of soft rubber, a thick sphere thereon of compressed paper, and a shell of gutta-percha which holds said paper sphere under compression.

5. A golf-ball comprising a springy center piece, a sphere thereon consisting of compressed paper, and a shell of gutta-percha which adheres to the paper sphere and holds the same under compression.
